Lumen Planus Accoya Rooflights


Lumen Planus Accoya new in rooflight design

Lumen Rooflight Ltd are proud to introduce our stunning new Lumen Planus Accoya flat roof skylight.

The Lumen Planus Accoya range will sit alongside the more traditional steel framed Planus skylights and will be constructed entirely from Accoya® timber - a leading high technology long-life wood, renowned for its durability, stability and sustainability among other benefits.

Available in a range of standard and bespoke sizes, this range of beautifully crafted rooflights are triple glazed and offer exceptional thermal performance with a whole frame U-Value of just 1.1Wm2K.

As with all Lumen rooflights, the Lumen Planus Accoya range is manufactured in the UK to the highest quality standards. The Lumen Planus Accoya incorporates triple glazed Pilkington Activ neutral solar control, self-clean glazing, argon gas cavities and Pilkington Optitherm S1 low-e glass.

Available as a fixed casement design or with manual or electric actuation (subject to size) for ventilation, the Lumen Planus Accoya is designed for use on a flat or low pitch roof construction including lead, zinc sheet, copper and asphaltic material. In addition to the rooflight, the Lumen Planus Accoya can also be supplied with our unique Lumen Planus Accoya insulated warm kerb system.

The Lumen Planus Accoya range of flat skylights also benefits from a wide range of colours including, RAL and Farrow & Ball and even a colour match service to your specific requirements. Unlike our other rooflights, the Lumen Planus Accoya also allows customers to specify differing internal and external colours rather than just a single option.
